Question

hey guys can somebody please help me with a math problem? ?? :))

Answer 1

"Rewrite the rational exponent as a radical by extending the properties of integer exponents."
the problem is attached below along with the rational exponent

Answer 2

\[\Huge \frac{2^{\frac78}}{2^\frac14}\]

Answer 3

Well, it will be better for you if you can express this as just ONE power of two.

The laws of exponents still apply, by the way:
\[\Large \frac{a^m}{a^n}= a^{m-n}\]

Answer 4

Okay!

Answer 5

Well, what is it?
\[\Huge \frac{2^\frac78}{2^\frac14}= 2^\color{red}{?}\]

Answer 6

does 5/8 go into the little question mark thingy?

Answer 7

Yes indeed.
\[\Huge \frac{2^\frac78}{2^\frac14}= 2^\color{red}{\frac58}\]

Answer 8

Now use this fact:
\[\huge a^{\frac mn}=\sqrt[n]{a^m}\]
and you'll have your answer ^_^

Answer 9

is the answer the third one down on that list? :o

Answer 10

Answer 11
